>Description:
daemon(8) provides the ability to write a pid file of the daemon it forks. It
also provides the ability to drop root privileges of the daemon it forks,
however, this feature prevents it from writing a pid file to /var/run.
Attached patch makes daemon(8) open the pid file descriptor before dropping
root privileges.
